How $5,000 grows at 5%
Compound interest earns returns on your returns — not just your original investment. At 5% per year, your money doubles every 14.4 years (the Rule of 72). Over 10 years, that compounds to a 1.63× multiplier.
In year 1, $5,000 earns $250 in interest. By year 10, the annual interest has grown to $388 — because each year's interest is calculated on a larger balance.
This is why longer holding periods matter so much. The later years do more of the heavy lifting, especially once the balance is large enough to generate bigger dollar returns each year.
